Make sure your student understands that a lack of situational awareness carries risks. Encourage them to keep their phone accessible, but to avoid focusing on the screen while they walk around.
Students should embrace the buddy system. By remaining in pairs or groups, no one is alone. That may decrease the odds that they will be targeted or, at least, ensure they have someone with them should something happen.
It ensures their property is secure when they are away. Plus, if they are in their room, it makes it much harder for someone unwelcome to make their way inside.
Never take a drink that was poured by someone else, alcoholic or not. There may be no way to determine what is in that cup, and many debilitating drugs aren’t detectable by taste, color, or smell.
Pepper spray, loud whistles, and other non-lethal devices can be smart to keep on-hand. They may deter an attacker from proceeding, increase the odds that a bystander will come to a student’s aid, or put a halt to an assault.
